Notes
"Sennit (also sinnet) is a type of cordage made by plaiting strands of dried fibre or grass. It can be used ornamentally in crafts, like a kind of macrame, or to make straw hats." (Source: Wikipedia: https://en.wikipedia.org/wiki/Sennit)
Knox New York Hat Company
The Knox Hat Company was founded in 1838 by Charles Knox. Knox Hatters expanded slowly at first from a modest shop at 110 Fulton Street to larger premises on Broadway, Nassau Street and eventually his corporate headquarters and shop on Fifth Avenue. The shop was described as “the most elegant establishment of its kind in the country“.
